Amanda Zolicoffer, 27, was filmed with Douglas Blansett, 75, by a flying camera operated by an anti-prostitution activist.

The pair were charged with public lewdness in connection with the incident in August last year in Oklahoma City, US.

Zolicoffer admitted the charge, the BBC reported.

She was sentenced to a year behind bars, according to court documents seen by the broadcaster.

The case against Blansett is still pending.

The drone was shown dropping to within a few feet of the vehicle where it filmed Blansett astride Zolicoffer in the front seat of the white pickup truck.

Footage: The video was filmed in private land where Bates claims he had the right to be

The duo separated after Zolicoffer, who was identified by her tattoo saying "Baby Gangster", saw the drone hovering overhead.

The footage was filmed by Brian Bates, an Oklahoma “video vigilante” who makes it his business to name and shame prostitutes and their clients via his website johntv.com .

Writing on his website, Bates said he had chosen the drone because his previous practise of "running up and opening car doors of people engaging in criminal acts" and then filming them was "pretty damn dangerous".

He said at least three people he has caught on camera were later convicted of committing murder and several of the women he had documented had themselves been murdered.

So instead of risking being hurt he decided "why not reduce the risk of personal injury and simply let a drone go in for the “You’re Busted Buddy” moment?".

In March, Bates followed Zolicoffer when she climbed into the truck of a suspected client and trailed it until it turned down a deserted road leading to a tire yard.

From an adjacent street, Bates then launched a drone and flew it above the parked Ford F-150. He then posted the footage on his YouTube page and showed it to police.
